Abstract
The invention discloses a 35kv cable intermediate connector which comprises a connector body. A conductor connection tube is arranged in the connector body, a cable extends into the conductor connection tube from two ends of the connector body, the conductor ends of the cable are arranged in the conductor connection tube and are symmetrically arranged, an insulation rubber layer is sleeved on the periphery of the cable in the connector body, a semiconductor shielding layer is arranged between the conductor connection tube and the insulation rubber layer, and a waterproof insulation rubber tape layer is arranged between the insulation rubber layer and the outer surface of the connector body. By means of the method, the 35kv cable intermediate connector is simple and compact in structure, good in insulation performance, capable of providing constant and durable radial pressure for a cable body, capable of breathing along with the cable, good in sealing and waterproof performance and reliable in running for a long time.
Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of 35kv cable intermediate joint.
Background technology
Elastic rubber material has " elastic memory " characteristic, just as spring.Cold-shrink technology claims the predilation technology again, promptly adopts mechanical means that the rubber parts of moulding is strutted in its elastic range in advance, is inserted in the plastics core then and is fixed.During installation, only need core is taken out, elastic rubbery body just shrink rapidly and lock ring in required installation position.
Insulating properties, heat-resisting quantity and the resistance to acids and bases of the cold-shrink type cable intermediate joint material of prior art itself are poor, cause the overall performance of transition joint poor, and the cold and hot bloated shrinkage in Electricity Federation is excessive, the waterproof sealing poor performance, and intensity is lower.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of 35kv cable intermediate joint, can have overall performance preferably, good stability, and useful life is strong, the water resistance height.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of 35kv cable intermediate joint is provided, comprise: joint body, be provided with conductor connecting tube in the described joint body, described cable stretches in the described conductor connecting tube from the two ends of joint body, the conductor end of cable is located in the described conductor connecting tube, and be symmetrical arranged, cable outer race in the joint body is provided with the insulation glue-line, be provided with the shield semiconductors layer between described conductor connecting tube and the described insulation glue-line, be provided with the waterproof insulation tape layer between the outer surface of described insulation glue-line and joint body.
In a preferred embodiment of the present invention, be provided with at least three conductor connecting tube in the described joint body.
In a preferred embodiment of the present invention, described conductor connecting tube inwall is provided with semiconductor self-adhesion belt.
In a preferred embodiment of the present invention, described waterproof insulation tape layer also is provided with copper mesh layers between the insulation glue-line, is provided with PVC protection belt between described copper mesh layers and the waterproof insulation tape layer.
In a preferred embodiment of the present invention, described cable and joint body junction are provided with waterproof insulation tape.
In a preferred embodiment of the present invention, be coated with constant force spring on the described copper mesh layers, outside described constant force spring, coat two-layer at least PVC protection belt.
The invention has the beneficial effects as follows: 35kv cable intermediate joint of the present invention is simple and compact for structure, and good insulating provides constant lasting radial pressure to cable body, and with cable same " breathing ", the water-tight performance is good, keeps operation reliably and with long-term.
